v0.37.0 - Exact-row retention: 46% fewer transfers, slower generation

v0.37.0 - Exact row retention saves 46% transfers but loses latency

First of the newly authorized four-to-eight research deliveries. The34.209-second
screen completes with all checked logits bit-identical and all48 scored tokens
per condition matching. Faithfulness, memory and acquisition pass; runtime fails.

1024 retained outgoing rows per layer reduce weight-plus-index H2D from
4,317,841,200 to2,330,056,432 B (46.0365%), but wall rises from1.891826 to4.241058s.
The192MiB cache is charged to both conditions, not a VRAM saving. Forward-call
totals also rise1.593093 to1.944361s: receipt serialization is not the sole loss.
Preserve the negative and stop this LRU candidate before a long matrix.

Three fresh short prefixes, FP32 OPT1.3B, separate declared warmups, imposed
4800MiB candidate budget and6500MiB reference allowance. Full reference GPU startup
means NO CPU-first capacity claim. Not stronger precision, larger-model deployment,
task-quality qualification or native-pivot evidence. v0.31/v0.34 used Qwen, not
ReLU; their negatives do not close ReLU predictive approaches.

639 CPU tests pass and a second raw audit matches exactly. Pre-inference review
caught an exact-boundary comparison bug; integer byte comparisons and a regression
test fixed it before measurement, without relaxing gates. Raw archive

Every member is restored/hash checked; checkpoint weights are not redistributed.
Final clean-tip full-suite validation is attached separately.

Complete #52, not
milestone10.
Next: separately freeze causal early acquisition with exact demand completion,
then stronger precision and scale comparisons. No stock tuning or native patch.
